Power supply and signal ground. Connect to the host circuit board ground.
Diagnostic serial port output.
Diagnostic serial port input.
Configurable digital I/O port 0. An internal weak pull up is provided when configured as an input.
Serial data output from the radio.
Serial data input to the radio.
UART/SPI flow control output. The module sets this line low to indicate it is ready to accept data from the host
on the RADIO_RXD or MOSI input. When the module sets this line high, the host must stop sending data.
UART flow control input. The host sets this line low to allow data to flow from the module on the RADIO_TXD
pin. When the host sets this line high, the module will stop sending data to the host.
16-bit pulse-width modulated output 0 with internal low-pass filter. Filter is first-order, with a 159 Hz 3 dB
bandwidth, 10K output resistance.
Configurable digital I/O port 2. An internal weak pull up is provided when configured as an input.
Configurable digital I/O port 1. An internal weak pull up is provided when configured as an input.
Configurable digital I/O port 3. An internal weak pull up is provided when configured as an input.
Reserved pin. Leave unconnected.
Power supply input, +3.0 to +3.63 Vdc.
Power supply and signal ground. Connect to the host circuit board ground.
Power supply and signal ground. Connect to the host circuit board ground.
Active low module hardware reset.
10-bit ADC input 0. ADC full scale reading can be referenced to the module’s +1.8 V regulated supply.
10-bit ADC input 1. ADC full scale reading can be referenced to the module’s +1.8 V regulated supply.
SPI master in, slave out function. This pin is an input when the module is operating as a master, and is an
output when the module is operating as a slave.
SPI master out, slave in function. This pin is an output when the module is operating as a master, and is an
input when the module is operating as a slave.
SPI active low slave select. This pin is an output when the module is operating as a master, and an input
when it is operating as a slave.
SPI clock signal. This pin is an output when operating as a master, and an input when operating as a slave.
Module’s +3.3 V regulated supply, available to power external sensor circuits. Current drain on this output
should be no greater than 50 mA.
Module’s +1.8 V regulated supply, used for ratiometric ADC readings. Current drain on this output should be
no greater than 10 mA.
Active high interrupt input to wake the module from timer sleep. Can be used to wake module on event, etc.
Active high output asserted when module wakes from timer sleep. Can be used to wake an external device.
Connect to the host circuit board ground plane.
Reserved pin. Leave unconnected.
Connect to the host circuit board ground plane.
